The rod P extending into the receptacle (L.

controls the admission-of the molten metal forced by the compressed air into the (lie or mold, the rod being movable by means of the meni ber P upon the shaft P A. spring tends to maintain the member P in the posi-' tion' for retaining the rocl in closed position, For operating both the air-controlling anal the metal-controlling valves the hencl levei" Q counter-Weighted at Q, aiid. pivot/e6; at Q to the frame of the machine is provioeoi, there being pivotelly connecteci to the hencl lever Q and the rock erin C the link R,

v to the projection R of the hanti lever the lug R on the shaft P the link R .ln oroler to operate the metal-controlling valve subsequent to the operation of air-controlling valve the link R isproviclecl With longitudinal slot R permitting of lost motion.

The shield E for protecting the operator from molten metal durino' the casting operation is sliclelply mountecl upon the columns B at the front of the machine so that the shield may be misetl above the die or niolzl when the latter is moved into or out from the casting position. and be between the or mold and the operator when the former is in the casting poeition. For raising anti lowering the shield toggle linkag is pro vidcd in which the separate ii: is 53 end S pivoted to each other are respectively El i V" otecl to the shield end the frame of the mechine with the link S pivotelly connecting the link 8 311111 the rock arm in operation sii'iugiog of the hand lei opens the colnpi'cssedi oncl low the sliieltl and so? sequent controlling valve to permit oi of the metal under pressure into the KDOlfil.

Still. another feature is u for preventing operation of illlu 2 Q5 until the (lie 01' molcl clompeii i position. Secured to the guide in of the hand lever Q is the stop 1.. provided with a slot T engogeehle by the hcnkl lever. ii hen the valves re closecl the bolt ll normally OZJiZQlHlS into the path oi. outward movement of howl level" pievent the swinging of the some, the hell creel V'pivotaily nmunj upon the ineni hei' T -eving one end portion c bolt W to retract the i 1e opposite entl portion in the path G L sect. frame of the me readily apparent unwei'ol. movement of the guides D 1" leases the he. cl lever through the "rod.

raising" levei' are swung hack to their origimil position, the henii lever then being locked in position by the bolt. The table is iovecl outwardly by the reel; nd pinion engagement and when new: the end of its outward movement the cope is raised from the drag by means of the $506k having the limiteii ZGillllh movement and intermediate connecting mechanism. Then the casting may be easily i-eniovecl by operating the plunger extending into the through its level",

What I claim as invention is: I 1. in a casting machine, the combination with e movable table and means foimoving the some, of e die or mold comprising at cling rigidlyniounted thereon and a cope slidaloly mountetl thereon, a, member beneath eeitl table and secured thereto, a yoke eziirying cope and slide bly engaging seicl memto, o, hell-crank mounted in said, member, connections between one enel of said hell crenl; :H'Kl said yoke, end 2. rod connected to the other end. of said hell-crank and having movement in one direction. limited for the purpose ileectihed,

2. in a casting machine, a base provided. with vei'ti'elly ciztendingg columns, :2, i'ecep 'ilOlQ fol containing molten metal ut the co posite end of said columns, e (lie or 1'1'l()lCl,.2t TQCiPI'OCHZblG table supporting the some, guicics for said table sliilehly mounted on said columns, c pin upon said, lie-so, a yoke elidchly engaging" seit pin and cminected to sail guides, and toggle linkage for 0 mm ing; szthl yoke.

3, in e. costing machine, at base provided th vertically extending colunii'ls, re receiiteclc For continuing molten. metal at the opposite eml oi said. C(llwll'llib, a (lie 01' mold, e i-eeiptoeahle iulilc suppoe'ting the some, guides ii eeizl table sliiuhly incur. too. on eeicl. coluemsi, e.
